To all whom it may concern:

lie it known that l, FRANK Gone, a citizen of the United States, residing at Camden, in the county of Camden and State of IIcw Jersey, have invented a new and useful Air-Brake, of which the following is a spccilication.

This invention relates to an improvement in an air brake and signal system, the primary object of the invention being the provision of an air brake system provided with a pneumatic and electric control, whereby the brake may be controlled either electrirally or pneumatically.

A further object of this invention is the provision of a combined auxiliary reservoir and brake cylinder, and valves mounted therein whereby the said bral e cylinder is controlled by either a pneumatic mechanism or electrical mechanism, for setting the emergency brake.

A further object of this invention is the provision of an air brake system, cont-rolled either by electrically operated means or pneumatically operated means, and pro vided with emergency mechanism whereby should the train become severed, the severed or rear portion will be automatically controlled, and theforward portion will be under the manual control of the engine man, whereby the forward portion of the train may proceed a safe distance ahead of the separated portion lessening the danger of a rear cndcollision, the engine man being no titled by a signaling device of the of said train.

is still further ohyect of this invention 1S severing the provision of an electro-pneumatic brake- ,and signal system, whereby the various sec- 49 tions of the train, or cars, are provided with individual electrical controls whereby the complete train may be brought to a stop; whereby all of the brake cylinders are placed under the control of the engine man by. a pneumatic or electrically operated means, thus providing a means or mechanism whereby should the electrical means fail, the pneumatic means will be at hand,

and vice versa.

A still further object of this invention is the provision of av construction of combined auxiliary reservoir and brake cylinder, whereby the said brake cylinder is controlled through the action of an emergency valve and this is located in the auxiliary cylinder, or tank, and so disposed to be of a frei ht train. Fig.

either operated electrically from a distant point or pneumatically.

A still further object of this invention) is the provision for recharging the auxiliary reservoir While the brakes are set, through a non-return inlet pipe as will presently appear. i

A. still further object 01'' the present invention is the provision for graduating the as application or release of the brake through a combination valve as Will presently zip I pear. I

With the foregoing and other object-sin view which will appear as the description proceeds, the invention resides in the comliinat-ion and arrangement of parts and in the details of construction hereinafter de-, scribed and claimed, it being understcodJ that changes in the precise embodiment of invention herein disclosedcan be made within the scope of what is claimed without departing from the spirit of the invention.

in the drawings-1 igure 1 is a diagrammatic view of the electro pneumatic traiinst; brake and signal system, as applied to the engine, intermediate cars, and the caboose",

b 2 is a detail longi tudinal sectional view of the form f,auX iliary tanl; and brake cylinder employed in '35 connection with this system, the parts being in the position they assume when setting the brake. Fig. 3 is an enlarged detail longitudinal sectional v'e'vv thereof, the parts being in normal position. Fig. fl is a simie so lar view employing a triple valve-in combination with the combined auiiiliary reser; voir and brake cylinder.

Referring to the drawings, the numeral 1 designates the train pipe of an air brake system, which is operated in the usual man'- ner, and supplied in the usual manner, and leading therefrom is the check \alvetrnonreturn inlet pipe 3, which leads to toe main casing or reservoir l. which is divided by U 0 means of the diaphragmor partition 3 into an auxiliary reservoir (aanpartmcul (3 and the brake cylinder compartment '4'.

The diaphragm or partition 5 is provided with an aperture having the valve seat 8, 155 which is adapted to be normally closed by the emergency valve 9 carried by the stem it) having: mounted thereon lhc coiled spring l0" between the valve 9 and the supporting or guiding spider ll. mounted within the chamber of the reservoir. while at the 0 other end of said stem 10 is mounted the ill?

The magnet 72 is energized through the circuit train will retain the circuit including the alarms 70 and Ti and batteries 69 open. It

Will thus he seen that should the conductors 68 and 68' be broken, due to the separation of the train, that the control cloctronuignet 72 will become deenergized, permit-tine; its armature to move due to the action'or the usual spring to close the circuit containing the batteries 69, and alarms TO and '71, thus giving the alarms in the rear car or caboose and indicating that the train is parted. At the same time, the armature of the control magnet 64: on the locomotive, ivill close the battery circuit operating signels 61 and respectively to indicate to the euginciucn that the train has parted.-

iviountcil'ui the locomotive end of the train is the usual air puinpoi', the air reservoir 58, and the manual control 5?), which controls the admission of the air through the application pipe 1, all as clearly shown and illustrated in diagram in Fig. 1.

From the foregoing description it will he soon that the auxiliary reservoir 6 is sup plied through. the auxiliary reservoir supply pipe and non return check valve 3 and the emergency chamber is supplied through its pipe 13, thus equalizing air pressure on both sides of the emergency piston 12.

To apply the emergency brake pneumatically, the train pipe pressure is reduced, causing air to low from the emergency chamber through the emergency supply pipe 13, and until the pressure is reduced below tens on of the cn'1ergc;:cy spring 10" of qergency piston l2 and its velvet), at .i time the auxiliary reservoir pressure ".I c the piston 1:? so as to unseat its valve 2111i, permitting the air to flow from the auxiliary reservoir to the brake cylinder,

. in the locomotive, thus attracting from its at the emergency chtunhcr release valve 17,

id nuiltaneously sealing the emergency chamber check valve 21, whereby the emergency chaniixer 1.3 is quickly relieved of pressure and causes the quick or rapid movement of the emergency piston 12 and its (e sto @ppo "mmdui .221,

This movement is simultlmeous regardless of the length of the "am, and may be repeated as often as desired. this means the train pipe premnre is free to flow direct to the auxiliary reservoir during this entire operation.

To release brake pneumatically, the train pipe pressure is slightly increased. ncing the piston 38 from normal position and one-eating the release valve- 32"), i

causing the bral-fe cylinder pres: ire to {low to the atmosphere through the exhaust pipe id a short perl, while the auxiliary pressure is equalizing u'ongh conduit 40' in the release chamber 30, suiiiciently to adjust the spring 88 and rcseating the release valve 39. T his operation may be repeated as often as desired, causing perfect graduation of all the brakes. ll so desired, to wl'iolly release the brake with the first operation,

the train pipe pressure is increased, to its fullest canacitv, and thus ating the .l f w. .2 1 lease an e rm :1 suilicient period to llllu'\V oi the pressure to escape :trom the brake. cylinder, before the auxiliary reservoir pressure eqnalizes in the releas chamber 30, the restricted port 40 prove- L ug the quick equalization of the auxiliary pressure in the release chain-be? 30.

To release the brake electrically, the release magnets 30 are energized, causing simultaneous n cvemcnt oi? all release 'alves tllllgllgllt'lllb the entire train, gaduating all brakes exactly the same, or releasing them as desired. By this means trains smoothness.

To operate he coi'nbination and check valves, electrically, the some being energized and {controlled at the engine end ot th'e train, tolrelease all the brakes graduall or Otlltll'lse, should the train part while in motion, the said valve is automatically energized by the control magnet- G l, whereupon the check valve 43 closes the admission of air to the application chamber of the combination valve or triple valve if used, through. ihe conduit 41, thus prevents ing the an. ma :ic application of the service brakes on nu forward section of the broken train, but in no way interfering v lith the automatic application of the brakes on the rear train sections which are separated, at the same lime he control magnet automatically Warns the engine man that his train has parted, so that by the simple pressure of his .i'inger upon the switch the brakes upon the forward section the train. may be operated, after positive information that the rear section has come to a full stop, thus avoiding a possible rear end collision.

lt is evident should the train part while. in motion, that the electromagnet 23 will be automatically energized by the control magnet 6 this action attracting the armature 20, seating the check valve 21 and preventing the escape of air from the emergency chamber. This will prevent the automatic application of the emergency brake on the forward section of the broken train, just as the check valve 43 will'prevcnt the automatic applicatimi ot' the service brake on the same section. The operation of the magnet 23 will in no way interfere with the operation of the magnet 19 although the operation of the magnet 19 will operate the valve 18 and consequently the valve 21.
